Abstract (en)
[origin: EP1975374A1] The casing has a sheet (150) with a thickness less than 1 millimeter, and ring sectors (120) circumferentially arranged in an end to end manner. Each sector has a plate (136) carrying an abradable material block (138) fixed on an inner surface of the plate. The plate has a circumferential dimension identical to that of the block. The block and the plate are separated from each other in circumferential direction so that a circumferential end part of the plate of each sector covers a corresponding end part of the block of the adjacent sector on all axial dimensions of the sectors.
